DRV8312-C2-KIT: IS DRV8312 compatible to drive 48V BLDC Motor???

Part Number: DRV8312-C2-KIT

Hi Guys,

I am able to drive 24V BLDC Motor with both Insta spin GUI and CCSV4.1(Insta_Spin_BLDC_GUI_project).

I want to drive 48V BLDC motor(Maxon EC Flat 60) in torque control mode using CCSV4.1 and DRV8312-C2-KIT.

I have following problems:

1.As per datasheet , drv8312 can handle supply voltage upto 50V. So can i use drv8312-c2-kit to drive 48V BLDC motor???

2.If yes then how it can be done in torque control mode???

please help.

Any help on above matter would be highly appreciated.

Thanks in advance.

    1. Yes, you can drive 48V BLDC with DRV8312-kit, please don't enable motor run into generator mode, will maybe damage the kit.
    2. Define the BUILDLEVEL as LEVEL5 in BLDC_Int-Settings.h to only enable current close loop.

    Thank you so much Yanming for your quick reply.

    Currently i am using InstaSPIN_BLDC lab project for my experiments.

    1.Please don't enable motor run into generator mode, will maybe damage the kit. 

       How to disable the motor to run into generator mode.???

       I mean in program where do i need to change the code??

    2.As per the BLDC_Int-Settings.h ,LEVEL5 defines commutation based on the BEMF Integration not the current closed loop.

    I have attached snapshot for reference.

    I think  you are talking about LEVEL6 which defines current closed loop.

    If it is true then which variable is responsible for changing the Current reference in program.????

    Thank you once again for your reply.

    Please help.
